摘要

Improved investment process for glue preparation for reinforced rosin paper in which melted reinforced rosin and water containing a dispersing agent are mixed first to provide an emulsion in which the melted reinforced rosin is the continuous phase and the water is the dispersed phase and the emulsion is subsequently inverted by the addition of water to provide an emulsion in which the water is the continuous phase and the reinforced rosin is the dispersed phase, wherein the improvement comprises using as dispersing agent one or more water-soluble compounds that provide in solution one or more anions of the formulas ** (see formula) ** Wherein, in the formula (I), r is a normal or branched chain alkyl containing from 4 to 18 carbon atoms; wherein, in the formula (II), r 'is a normal or branched chain or alkyl alcohol or a fused ring cycloalkyl containing from 10 to 20 carbon atoms; where, in the formulas (I), and (II), k is an integer having any suitable value determined by the method that has been previously defined in this specification.
